Following its abandonment, the Aquarium sign fell apart, reading only "UARIU", and the windows were covered with black cloth. The interior has a wet and dirty floor, with few cracked tanks remaining on shelves, and some leftover containers of food, plastic castles, and a dusty counter next to a dusty cash register and empty coffee mug. Above the aquarium are several apartments.
Lemony Snicket follows Nurse Dander into it, who has captured Ellington Feint, believing she is Cleo Knight. Lemony pretends to be a delivery person and gives Ellington his coat and hat so that she can escape, before dropping a fish bowl out of the window to distract her so he can escape.
